FERRULE FOR UMBRELLAS AND CANES.

SPECIFICATION forming part of Letters Patent No. 408,965, dated August 13, 1889.

Application filed April 25, 1889.

To all whom it may concern:

Be it known that 1, JOHN A. FURMAN, a citi zen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have inven ted a new and useful Improvementin Tips or Ferrules for Umbrellas and Canes, of which the following is a specification. 1

The object of my invention is to provide a new tip or ferrule for umbrellas and canes, consisting of a slug of suitable metallic substance firmly held or embedded in a tube or cylindrical case of celluloid or analogous material.

My invention is illustrated by the accompanying drawings, in which similar parts throughout the several views are represented by similar letters.

Figure 1 is an elevation of the plunger or male die in which my improved tip or ferrule is molded; Fig. 2, an elevation of the female die. Fig. 3 is a plan view of the female die; Fig. 4, a plan view of the plunger. Fig. 5 is a view, partially sectional, of my improved tip or ferrule. Figs. 6, 7, 8, and 9 are elevation and plan views of two forms of suitable slugs.

The female die 13 C is adapted to receive the slug and celluloid, and after the plunger descends and the die is subjected to heat and pressure gives form to my improved ferrule or tip. The slug is first dropped in the female mold and a piece of celluloid or similar substance of sufficient size is placed above it. The plunger D descends and the surplus celluloid is allowed to escape into the overflow c. The operation is similar to that of the ordinary plunger-die. The celluloid tip when formed has substantially the shape shown in Fig. 5, in which the slug F is similar in form to that illustrated in Fig. 6. WVhen, however, a slug of the form shown in Fig. Sis used, the celluloid is forced into the hollow portion e of the slug instead of the shoulder f of the other slug being forced into the celluloid. It will be found that the first form of slug Serial No. 308,586. (No model.)

namely, the one illustrated in Figs. 5, 6, and 7is preferable, because it is more simply made and because the shoulder f is undercut, thus preventing the celluloid from shrinking away from it; but both forms and other suitable forms may be used without departing from the spirit of my invention. The improved tip, as shown in Fig. 5, consists of a suitable slug of metal embedded in a cylindrical case of celluloid, which is cap-shaped, and adapted 5 5 to fit or slip on the stick of the umbrella or cane. As is well known, when celluloid and analogous pyroxyline substances dry or season they shrink, and for this reason I prefer to mold my tip or ferrule so that a shoul- 6o der of the celluloid overlaps the slug, as shown at 0, Fig. 5. In such a tip or ferrule shrinkage of the celluloid serves to hold the slug more closely, and by reason of this shoulder no crack or crevice between the slug and cap will occur when the celluloid shrinks.

The advantages of my new tip or'ferrule are many. It is cheaply and simply made. The size of the diameter of the cap can be regulated to fit any cane or umbrella stick, and by use of molds adapted to shape and form any number of ferrules at one molding. The ferrules can be made in large quantities at comparatively small expense.

Celluloid and similar pyroxyline materials, as has been previously stated, shrink upon seasoning, and hence the cap of my improved ferrule will tend to adhere more closely to the stick of the cane or umbrella as it is used.

Having fully described my invention, what I desire to secure by Letters Patent is- As a new article of. manufacture, a tip or ferrule composed of a cap of celluloid or similar pyroxyline material with a metal slug embedded therein, as and for the purposes set forth.

JOHN A. FURMAN.
